Global Temperatures are Soaring

Graph: Global Temperatures with trend line: 1880 - 2015 (NOAA)
  • The black line shows the “long-term trend” of the “average global air temperatures” from 1880 to 2015 produced by the US National Oceanic and Atmospheric Administration (NOAA)
  • The upward trend in temperature continues after 2015.
  • Below I describe how you can get the most recent graph.
  • Temperatures have increased by 0.67°C per century between 1880 and 2014. 

More recent graphs: The same message

All the more recent graphs reinforce the message gained from the above 2015 graph.
See: NOAA global climate reports


The latest years here, 2014 & 2015, are the hottest.

  • Each “temperature anomaly” is the temperature difference from the average temperature shown in degrees Fahrenheit.
  • The average global temperature anomaly for each year is shown by a rectangle:
    • The blue rectangles show temperatures below the average
    • The red rectangles show temperatures above the average
  • The hottest year on record was 2015. (See the right-most red rectangle on the graph.)
  • The second hottest year was 2014.

Generate the latest Temperature Graph

  • Go to the Global Time series page:
  • https://www.ncdc.noaa.gov/cag/time-series/global
  • Select Time-scale = “Annual”
  • Tick “Display Trend”
  • Select “trend per Century
  • Select Region = “Global”
  • Select Surface = “Land and Ocean”
  • Click “Plot”

The temperature increases are already damaging.

We are already experiencing significant impacts of this warming:

  • Hotter weather with extended fire seasons
  • Droughts, bush-fires and floods are more frequent and intense
  • The distribution of plants and animals is shifting towards the poles,
  • The planet is losing ice
  • The oceans are rising faster

It is not sustainable for us to have global temperature increasing like this.
